SDN and NFV is the next phase of technology change which will help service provider to launch the services in single click. This is all about the programmability of the networks by using open source software defined network controller.

In previous post we have covered basics of vxlan and it's deployment models. In this post we will be covering the different ways of VxLAN control plane deployment models.
BGP based VxLAN Control Plane – BGP is the industry preferred protocol for both ease of implementation and scalability. BGP does scale well as it is responsible to the routing of the internet and can easily be adapted to support MAC to VTEP IP address mapping under another address family (That's BGP is called Multi Protocol). The only issue with BGP is the speed at which it often takes to converge after a network change.
LISP based VxLAN Control Plane – The LISP control plane has been talked about heavily as a scalable hierarchical option for the VXLAN control plane however LISP as a whole has never really got much traction. LISP doesn’t have a traditional flood to learn mechanism and learns new routes or mac to VTEP IP mappings.
OpenFlow based – There are a number of VXLAN deployments that use Openflow or XMPP in order to remove the restriction of multicast within VXLAN deployment.
TLV based – The TLV option is often used as a quick and easy way to manipulate existing protocols to transfer new information with IP/VTEP mappings.
